UL489 or UL1077?What are your Circuit Protection Requirements?
An understanding of circuit types and circuit protection products is critical to ensure their proper application.See NEC Sections 100, 430 and 409 for definitions.
The proper sizing of an overcurrent protection device is the responsibility of the customer and should be determined using the applicationstandards of the NEC (National Electric Code), CEC (Canadian Electrical Code) or other applicable standards. Per fine print note of 2008 NEC
Section 100 "A current in excess of rating may be accommodated by certain equipment and conductors for a given set of conditions.Therefore, the rules for overcurrent protection are specific for particular situations."

UL489Branch Protection
UL1077Supplementary Protection
• UL489 Listed or Recognized• CSA C22.2 No. 5• International ratings available depending on breaker type
• UL Recognized under UL1077• CSA 22.2 No. 285• IEC 60947-2 or IEC 898
Function
• Opens automatically on Overload and Short Circuit when properly applied with-in its ratings
• Protects wire and cable against Overload and Short Circuit
• Opens automatically on Overload and Short Circuit• Provides additional equipment protection where branch circuit protection isalready provided or not required
• Not suitable for the protection of branch circuit conductorsApplications
• Branch circuit protection in control panels, panelboards, switchboards andmotor control centers
• Motor overload and motor short circuit protection (UL489 Recognized motorcircuit protectors) for control panels and motor control centers
• Used within appliances or other electrical equipment such as control circuits,control power transformers, relays, PLC I/O points and lighting circuits
• Ideal replacement for fuses that are applied as supplementary protection
Features
• Bolted down or DIN-rail mounted• External handle mechanisms available• Field mounted accessories• Stand alone branch circuit protection• Various levels of protection (curve type)• High voltage and interruption levels (up to 100 kAIC @ 480V)
• DIN-Rail mounted• Field mounted accessories• Current limiting• Various levels of protection (curve type)• 10 kAIC @ 240 VAC• 6 kAIC @ 277 VAC and 5 kAIC @ 480 VAC• 10 kAIC @ 65 VDC
kAIC = thousands of Amps interrupt capacitySummary
A Supplementary Protector can’t Be used for Branch Circuit Protection.Understanding the difference between Branch Circuit Protection and Supplementary Protection helps to ensure their proper use.

WMZT Miniature Circuit Breakers
ApplicationsFeeder and Branch Circuit Protection
• Convenience receptacle circuits(internal / external)
• Motor control circuits• Load circuits leaving the equipment
(external)• HACR Equipment (Heating Air
Conditioning, Refrigeration)• PLC I/O points• Computers• Power supplies• Control instrumentation• Relays• UPS• Power conditioners
OverviewEaton WMZT miniature circuit breakers offeroptimum and efficient protection for branchand control circuits up to 40 amps. TheWMZT series is available with C or D tripcharacteristics in accordance with UL489.These circuit breakers are current limiting,which means they interrupt fault currentswithin one half cycle of the fault. The WMZTseries is DIN-rail mountable and can beused in branch circuit applications.
Listings• UL Listed and Recognized under UL 489Category DIVQ File E7819Category DKSY2 File E7819Category DIHS E64983
• CSA 22.2, No. 5 File 245545• CE LVD 2006/95/EC• IEC/EN 60947-2
Features and Benefits• Complete range of UL489 listed DIN railmounted miniature circuit breakers up to40 ampere current rating
• Single pole, two-pole and three polemodels
• Current limiting design provides fast shortcircuit interruption that reduces thelet-through energy, which can damage thecircuit
• Suitable for branch circuit device protection• Thermal-magnetic overcurrent protection— two levels of short circuit protection,categorized by C and D curves
C curve magnetic trip point:5 to 10 times the rated current,typically used for smalltransformers, pilot devices, etc.D curve magnetic trip point:10 to 20 times the rated current,typically used for transformers orloads with very high inductive loads.
• Trip-free design — breaker cannot bedefeated by holding the handle in the “ON”position
• Captive screws cannot be lost• SWD (switching duty) rated circuit breaker— suitable for switching fluorescentlighting loads (In � 20A)
• Fulfills UL 489, CSA C22.2 No.5 and also IEC60947-2 Standard
• Can also be used in applications for whichUL 1077 or CSA C22.2 No.235 are alsoallowed
• Field installable shunt trip and auxiliaryswitch subsequent mounting (SeeAllowable Combinations page)
• Module width of only 17.7 mm (per pole)• Contact position indicator (red / green)• 35 mm DIN-rail mountable, utilizing springclip
• Suitable for reverse feed applications

WMZT Miniature Circuit Breakers
Tripping CharacteristicsEaton WMZT miniature circuit breakers are available with “C”and “D” tripping characteristics.
TTyyppee CC ttrriipp ccuurrvvee:: 5 to10 InCC--ccuurrvvee devices are suitable for applications where mediumlevels of inrush current are expected. Applications include smalltransformers, lighting, pilot devices, control circuits and coils. C-curve devices provide a medium magnetic trip point.
TTyyppee DD ttrriipp ccuurrvvee:: 10 to 20 In
DD--ccuurrvvee devices are suitable for applications where high levels ofinrush current are expected. The high magnetic trip point preventsnuisance tripping in high inductive applications such as motors,transformers and power supplies.
Eaton WMZT devices are current limiting, which means they interrupt fault currents within one half cycle of the fault. Currentlimiting devices offer superior protection by reducing peak let-through current and energy.
